It will be apparent that the movement of the wedge in one direction or the: other applies a force upon the upper edge of the jaws 1 and thereby forcing the jaws in one direction or another through the medium of the wedge, thus providing a positive means of clamping and releasing the jaws from the trolley wire.

Theengagementof the wedge with the jaws maintains the jaws in either their opened or closed position thus avoiding the use of springs for maintaining the jaws in an open position, as is the case with some types of clamps.

Modifications will suggest themselves to those skilled in the art, therefore, I wish to be lim supporting stud pivotally mounted upon the pintl and having a threaded boss to receive a hanger and a longitudinally movable wedge member having projecting flanges on one face arranged to form a longitudinal groove on each side of the supporting stud, the grooves diverging and converging and a portion of the jaws positioned in the grooves to engage the sides thereof whereby a movement of the wedgemember in onev direction will close the jaws upon, the wire and a movement in the other direction will release the in their open position when not in engagement with the conductor.
